Once upon a time, this would have been a decent discount. Of course, I'm referring to the days when it was plausible to get gas for $0.99/gallon. A blanket 10% discount was pretty nice. Nowadays, with gas routinely pushing $5/gallon, we're down to 2-3%. That's a rounding error. Sure, it adds up, but if I have to do anything new to get the discount at all, then it quickly becomes not worth my time.
